Biology EOC review

Front

What is the function of tRNA in protein synthesis?

Back

tRNA (transfer RNA) transports amino acids to the ribosome, where proteins are synthesized.

Front

How does aerobic respiration differ from fermentation in terms of energy production?

Back

Aerobic respiration results in more energy compared to fermentation.

Front

What is gene flow and how does it contribute to genetic variation?

Back

Gene flow is the transfer of genes between populations, which increases genetic variation and can lead to evolution.

Front

Why do muscle cells and blood cells have different functions?

Back

Different genes are activated in muscle cells than in blood cells, leading to their distinct functions.

Front

What stage of mitosis is characterized by the separation of sister chromatids?

Back

Anaphase is the stage of mitosis where sister chromatids are pulled apart to opposite poles of the cell.

Front

Define mitosis.

Back

Mitosis is the process of cell division that results in two genetically identical daughter cells.

Front

What is the role of ribosomes in a cell?

Back

Ribosomes are the cellular structures where protein synthesis occurs.

Front

Explain the process of natural selection.

Back

Natural selection is the process by which organisms better adapted to their environment tend to survive and produce more offspring.

Front

What is the difference between DNA and RNA?

Back

DNA (deoxyribonucleic acid) stores genetic information, while RNA (ribonucleic acid) plays a role in protein synthesis.

Front

What is a mutation?

Back

A mutation is a change in the DNA sequence that can lead to variations in traits.
